Silly segmentation strikes again. You probably didn't think about it if you read about HP's proposed new wristwatch in today's business pages of the NY Times. Did you know that between 2008 and 2010, sale of watches fell 29% in the 18-24 age group, rose 33% in the 35-44 age group and 104% for those 65 and older? Okay, no big deal, you say. NPD Group, keeper of these stats, reports this as though a 6-year age range, a 9 year age range, and a 25+ year age range have comparable purchasing characteristics within the range. Misinterpretation opportunity looms large -- and if you are a watch manufacturer, it may not be time to plan on closing the business within the next 10 years based on whether 'young shoppers' may care. In fact, it would have been great to ask a few older adults if they'd like HP's proposed wireless watch (with hands!) which could be programmed with canned responses and might have utility -- maybe even expanding the PERS opportunity downward.
